About a week ago i thought to give them a try and made a little test deposit. But not even this 1st step was working out: How I learned later, the coin was "in maintenance" and "deposits offline". Still HitBTC let me deposit and not even gave a warning about the offline status.
After the coins arrived at their given address they moved them away to another address very soon. When I opened a support ticket about this issue they came back with standard text. After requesting an update some days later, they did not respond but just closed the case. I reopened another one including all the info of the original one with the request to refund my payment and still get no answer for days now.
So even if they would do the refund eventually, it is me staying with the risk as I can not sell these coins in the meantime. So I can only warn everybody to use this exchange.
It's definitely their fault for not warning users but If your funds are still there (on your HitBtc balance) then this is normal (for most of exchanges actually) because you don't really control that address but If you ever decide to make a withdrawal, the funds will come from an address that you didn't deposit to. So again, If the funds are in your account, just wait until the maintenance is finished.
Thanks for info! Still the problem is, that they coins are NOT at the HitBTC balance. They just transfered them to another address they own (seen by a block explorer) but did not made them available in my account. So they are locked in until they put their fingers out of their asses. And this takes now for more than a week. All in this time the value could drop and I would have to sit at the losses.
